Abstract

The invention relates to a white food rubber slab which is prepared from the following raw materials in parts by weight: 2-10 parts of natural rubber, 0-5 parts of cis-1,4-polybutadiene rubber, 1-5 parts of butadiene styrene rubber, 0-0.5 part of S, 0.01-0.15 part of M, 0.05-0.2 part of DM, 0.1-0.8 part of zinc oxide, 0.1-0.4 part of stearic acid, 1-3 parts of titanium white, 20-30 parts of calcium carbonate and 0.5-2 parts of product oil. The invention also relates to a preparation method of the white food rubber slab. The preparation method comprises the following steps: (1) mixing and banburying; (2) primary rubber mixing and thick slab pressing; (3) standing and oxidation; (4) secondary fine mixing and fine slab pressing; (5) tertiary refining and thin slab pressing; and (6) vulcanizing. The preparation method is low in preparation cost, lowers the enterprise input, and increases the economic benefits. The prepared rubber slab can be used for food packaging and the like, has no toxicity or harm, and ensures the use safety.

Description

technical field [0001] The invention relates to a preparation method of a food rubber sheet, in particular to a preparation method of a white food rubber sheet. Background technique [0002] Plastic sheets for food need to go through safety monitoring.
